"A lot of people come in with chronic and acute health care conditions," said Bolton.

Bolton said they book about 45,000 people per year in Metro Corrections.

The jail already has recorded seven deaths this year, but two raised questions.

According to corrections records, Savannah Sparks died from opiate abuse and withdrawals in April.

Samantha George died in August, but as of late October, the manner of her death remained under investigation

"I found some errors, errors in terms of expedience in which the two individuals were seen and expedience when they were put on the doctor's list for the doctor to see them," said Bolton.

Bolton points to Corizon, which has a $5.5 million contract to provide jail health care. Several of its employees have recently resigned.

Metro Corrections is seeking a compliance monitor to make sure the terms of that contract are met.

Corizon said it will work with that monitor as part of its "ongoing efforts to continuously improve the delivery of health care services to our patients."

Bolton pointed out he has made other changes. A detox nurse has been added as well as new detox protocols.

"We've amped up our referral process on the front end. People who are in chronic or acute healthcare conditions may be deferred to University (of Louisville) Hospital before we admit them here," said Bolton.

Bolton said investigations into the deaths of the two female inmates are ongoing.
